img1 = gf.land.options(scale='50m')

Out[2]:
show the same map zoomed in to the San Francisco, California, USA area. So far so good.
In [3]:
img1.opts(xlim=(-122, -123), ylim=(37, 38))
Out[3]:
show oceans, land masses, and (oceans, coastlines, land masses) overlaid. So far so good.
In [4]:
(gf.ocean + gf.land + gf.ocean * gf.land * gf.coastline * gf.borders)
Out[4]:
Now show a single panel with land and oceans overlaid. This produces a blank plot.
In [5]:
img2 = gf.land.options(scale='50m') * gf.ocean.options(scale='50m')
